scope:

This International Standard deals with the safety of electric motor-operated or magnetically driven:

- HAND-HELD TOOLS (IEC 62841-2);

- TRANSPORTABLE TOOLS (IEC 62841-3);

- LAWN AND GARDEN MACHINERY (IEC 62841-4).

The above listed categories are hereinafter referred to as "tools" or ″machines″.

The RATED VOLTAGE is not more than 250 V for single-phase a.c. or d.c. tools, and 480 V for three-phase a.c. tools. The RATED INPUT is not more than 3 700 W.

The limits for the applicability of this standard for BATTERY tools are given in K.1 and L.1.

This standard deals with the hazards presented by tools which are encountered by all persons in the NORMAL USE and reasonably foreseeable misuse of the tools.

Tools with electric heating elements are within the scope of this standard.

Requirements for motors not isolated from the supply, and having BASIC INSULATION not designed for the RATED VOLTAGE of the tools, are given in Annex B. Requirements for rechargeable BATTERY-powered motor-operated or magnetically driven tools and the BATTERY packs for such tools are given in Annex K. Requirements for such tools that are also operated and/or charged directly from the mains or a NON-ISOLATED SOURCE are given in Annex L.

Hand-held electric tools, which can be mounted on a support or working stand for use as fixed tools without any alteration of the tool itself, are within the scope of this standard and such combination of a HAND-HELD TOOL and a support is considered to be a TRANSPORTABLE TOOL and thus covered by the relevant Part 3.

This standard does not apply to:

- tools intended to be used in the presence of explosive atmosphere (dust, vapour or gas);

- tools used for preparing and processing food;

- tools for medical purposes;

NOTE 1 IEC 60601 series covers a variety of tools for medical purposes.

- tools intended to be used with cosmetics or pharmaceutical products;

- heating tools;

NOTE 2 IEC 60335-2-45 covers a variety of heating tools.

- electric motor-operated household and similar electrical appliances;

NOTE 3 IEC 60335 series covers a variety of electric motor-operated household and similar electrical appliances.

- electrical equipment for industrial machine-tools;

NOTE 4 IEC 60204 series deals with electrical safety of machinery.

- small low voltage transformer operated bench tools intended for model making, e.g. the making of radio controlled model aircraft or cars, etc.

NOTE 5 In the United States of America, the following conditions apply:

This standard deals with tools used in non-hazardous locations in accordance with the National Electrical Code, NFPA 70.

NOTE 6 In Canada, the following conditions apply:

This standard deals with tools used in non-hazardous locations in accordance with the Canadian Electric Code, Part 1, CSA C22.1, and General Requirements - Canadian Electrical Code, Part II, CAN/CSA-C22.2 No. 0.

This document applies to the design of pedestrian controlled walk-behind

- cylinder lawnmowers;

and

- rotary lawnmowers

equipped with

- metallic cutting means; and/or

- rigid non-metallic cutting means; and/or

- non-metallic cutting means with one or more cutting elements pivotally mounted on a generally circular drive unit, where these cutting elements rely on centrifugal force to achieve cutting, and have a kinetic energy for each single cutting element of greater than 10 J.

NOTE 101 Machines that have non-metallic cutting means and a kinetic energy for each single cutting element of less than or equal to 10 J are considered to be lawn trimmers.

This document does not apply to

- robotic lawnmowers;

- remote-controlled lawnmowers;

- flail mowers or flail-type attachments;

- scissors type lawnmowers;

- grassland mowers;

- sickle bar mowers;

- towed/semi-mounted grass-cutting machines;

- scrub-clearing machines;

- lawn trimmers and lawn edge trimmers;

- lawn edgers;

- grass trimmers;

- brush cutters;

- brush saws;

- agricultural mowers;

- trailing seat/sulky units;

- ride-on machines;

- non-powered lawnmowers;

- combustion engine powered lawnmowers;

- hybrid and fuel cell powered machines and associated charging systems; and

- garden tractors or their attachments.

NOTE 102 Robotic lawnmowers are covered by IEC 60335-2-107, and will be covered by a future part of IEC 62841.

NOTE 103 Lawn trimmers and lawn edge trimmers are covered by IEC 60335-2-91.

NOTE 104 Lawn trimmers, lawn edge trimmers, grass trimmers, brush cutters and brush saws will be covered by a future part of IEC 62841.

NOTE 105 Lawn edgers will be covered by a future part of IEC 62841.
